In operating rooms, communication errors between the surgeons and assistants may be a source of inefficiency or error. In laparoscopic surgery, the endoscopic camera is an essential device, usually held by a human, and, why not, by a robotic assistant. In this paper, a novel four-DoF isotonic foot interface for controlling an endoscope positioner is proposed, featuring two rotational and two translational...
In laparoscopic surgery, surgeons often encounter paradoxical vision according to their position against the camera position. Such a paradoxical vision evokes confusion and surely deteriorates surgical performance. Previous researches indicated inverted mirror image is useful to compensate this problem though upside-down inversion makes depth sensation perplex. To solve the dilemma, we proposed modified...
In this paper, we built and tested the port camera, a novel, inexpensive, portable, and battery-powered laparoscopic tool that integrates the components of a vision system with a cannula port. This new device 1) minimizes the invasiveness of laparoscopic surgery by combining a camera port and tool port; 2) reduces the cost of laparoscopic vision systems by integrating an inexpensive CMOS sensor and...
